TCP, UDP, DCCP,... Cause: Multiplexer guard bands are too small or wires too close together. Prevention: Increase the guard bands or move or shield the wires. Cause: Sudden increase in electricity Prevention: Shield or move the wires Cause: Signals from several circuits combine. Prevention: Move or shield the wires. IPv4, IPv6, IPsec, ARP, RARP,... Cause: Movement of electrons (Thermal Energy) Prevention: Increase Signal Strength (Increase SNR) Cause: Poor connections (causing signal to be reflected back to the source) Prevention: Fix the connections, or tune equipment.
